Apnlication filed January 15,1906. Serial No. 296,080.

To a, whom it may concern: broken away, a portion of the track-support Be it known that I, PATRICK A. OBRIEN, belonging to the device shown in Fig. 1; and a citizen of the United States, residing at Fig. 3 is a section on the line 3 3 in Fig. 2. Boston, in the county of Suffolk and State of Referring to the drawings, and to the par- Massachusetts, have invented an'Improveticular embodiment of my invention there ment in Devices for Holding Charts or the illustrated, the hanger or holding device there Like, of which the following description, in shown is provided with a track-support 6o connection with the accompanying drawwhich herein is shown comprised in two sepaings, is a specification, like letters on the rate but similar pieces a, a. These may be drawings representing like parts. constructed in any suitable shape and of any My invention relates to devices for holding suitable material, but I prefer in practice to charts or the like, and particularly to means form them of elongated strips of sheet metal 5 for conveniently and effectively holding each having its upper and lower sides I) turned maps, charts, or other like objects in an exover, as best shown in Figs. 2 and 3, to protended position upon the wall of a schoolvide guideways for and to suitably retain in room, lecture-hall, or other place where it is place adjustable hangers c and c, which redesired to exhibit them. semble, generally, the hanging bracket of a My invention has, among other objects, curtain-fixture. the production of a map or chart holding de The supports a, a are provided with any vice which may be readily adjusted within suitable means, such as the screw-holes reasonable limits to give suitable hanging shown, by which they may be fastened in a support to a chart of any width, permitting horizontal position upon a backboard A the the latter to be readily and easily hung up or latter being permanently secured or othertaken down, as desired. 7 wise fastened to the wall of the school or My invention has particular application to other room. By constructing the support the holding of charts or maps inaschool-room ing member in two parts they may be fasor lecture-hall. It is usual to mount such tened to the board, with their ends abutting 30 maps upon a roller similar to an ordinary or at any desired distance apart, and thereby curtain-roller and provide the same with fixincrease or diminish the range of adjustment tures similar to ordinary curtain-fixtures, the obtainable from the holding device to any latter secured to a backboard or base which desired extent. It will be obvious that they is usually removably secured to the wall of may be made up in standard strips of moder- 5 the room. It has been customary to provide ate length and three or more of them ara special backboard with perinanentlyatranged in series, so that by shifting the tached fixtures thereon for each map, the hanger c from one support to the next adjadifferent widths of maps with different lengths cent one they may be made to hold a chart of rollers making the fixture non-inter M of any width from the smallest to the 9 changeable. Through the use of my invenlargest. tion a single backboard permanently secured The hanging members or brackets are each to the wall, if desired, with a single set of fixmounted upon a base d, which has the elontures may be employed for a variety of differgated laterally-extended feet a underlying ent widths of maps, thereby saving needless the overturned sides I) of the track-support, expense. so that the hanger can be moved lengthwise My invention will be best understood by the same while effectually retained in place, reference to the following description, when whatever position be given it. Upon the taken in connection with the accompanying hanger-base is formed a lug f, into which is illustration, of one specific embodiment threaded a set-screw g, the end of which may I00 thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings, Figure 1 shows a map hung in position upon a hanger or holding device embodying one form of my invention. Fig. 2 shows, on an enlarged scale, partially be made to engage with any one of a series of corrugations or serrations in the bottom of the trackway, these being readily formed in the illustrated embodiment by merely punching up a series of projections "n from the 5 bottom of the strip.

When the set-screw is loosened, the hanger may be shifted to any position Within the limits of the supporting-strip and at the de sired point may be secured by merely turning the set-screw to engage the bottom of the support, which forces the feet 6 out against the sides 6 of the supporting-strip, as seen in Fig. 3, and firmly locks the hanger in position.

The hanging member has an aperture i, provided with an open mouth j, after the usual fashion of curtain-holding brackets and of suitable size to' engage with the flattened stem, which is usually employed at one end of the map-roller R. The other hanger c (not shown) has the usual closed aperture, as is customary in curtain-fixtures, for receiving the opposite and rounded stem of the roller. The mouth of the opening in the l fixture i is slightly contracted, so as better to l l l l retain the same in position, the mouth, how ever, at its entrance, as well as the mouth and the entire aperture on its inner face, being preferably beveled, so that the stem if pushed toward the mouth of the opening will naturally tend to find its place within the same.

lVhen this device is employed, the base or backboard A, of suitable length to carry the Widest maps to be exhibited, may be permanently secured upon the wall of the room ini stead of removably secured thereto, as herel tofore. The track-supports (t a are then l screwed in a horizontal position to the face l of the backboard. This single and permal nently-secured fixture carrying the adjustable sliding brackets may then be used to hang maps of varying width, each of which requires to be provided only with the usual l roller-fixture and without the necessity of individual brackets or other supporting means therefor.

All the parts of this device may, if desired,

be nickeled or otherwise that when in position upon the wall of a room it will serve as an ornamental fixture.

l Vhile I have herein shown and described one form of my invention, it will be under stood that the same is in no wise limited to the details or form and arrangement of parts disclosed, but that extensive modifications may be made therein without departing from the spirit of my invention.

I claiml. A chart-holding device comprising a backboard, two separated but alined supporting members, iach consisting of sheet metal having upper and lower overturned edges, and having formed integrt'tl therewith a series of horizontally-disposed corrugations, and a hanging member or bracket adapted to be received in each support for longitudinal movement therein, and pro vided with means to engage with said eorrw gations. v 2. A chart-lmlding device comprising :1 backboard, a pair of spaced but alined supporting members each formed of sheet metal and provided with overturned edges forming a trackway, and further provided with integral corrugations struck up from the body of said member, and a hanging lnacket for each support adapted to receive chart or map. and provided with a base adapted to be received. in said overturned edges of the support, and further having a sct-srrew adapted to be adjustably engaged with the desired corrugations.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
